An encapsulated perfume composition for use in personal care products adapted to be applied to, and left on, the skin or hair of a human or animal subject, said encapsulated perfume composition comprising one or more polyurea capsules having a volume average diameter of 20 to 90 microns, and a capsule shell weight, which is 5 to 40% based on the total weight of the capsules.

Capsule composition

The application describes a process for the preparation of microcapsules, wherein the microcapsules have a volume average diameter d of 15 to 90 &#x3bc;&#x3b7;&#x3b7; and a percentage of the shell weight of 3 to 40%, with reference to the total weight of capsules, wherein the shell of the microcapsules comprises at least one polyurea and the core comprises at least one lipophilic component, comprising the step of adding hydroxyalkylcellulose to a dispersion of polyurea microcapsules, microcapsules and their uses.

Process for preparing microcapsules having a polyurea shell and a lipophilic core material

The application describes an aqueous dispersion of microcapsules, wherein the shell of the microcapsules comprises at least one polyurea and the core comprises one or more lipophilic components with the proviso that the core does not contain a fragrance, and having a percentage of the shell weight with reference to the total weight of the capsules of 5 to 40% and wherein the microcapsules have a volume average diameter of 15 to 90 &#x3bc;m and the dispersion comprises hydroxyalkylcellulose and the use of such a dispersion.

Microcapsules comprising hydroxyalkyl cellulose

A process for producing microcapsules containing a shell and a core of a liquid water-insoluble material is disclosed. The microcapsules are prepared using a bifunctional isocyanate, an anionically modified diisocyanate, a bifunctional amine, and a protective colloid. The protective colloid is a polyvinyl alcohol copolymer having hydrolysis degrees from 85 to 99.9%.

Process for producing microcapsules

The present invention relates to the use of a composition comprising a peroxidic compound and a particular, generically defined copolymer for tooth bleaching.

Polymers which are suitable for use in cleaning compositions are described. The polymers are comprised of at least three different monomers. The types of monomers and ratios of the monomers in the polymers are further disclosed. Cleaning compositions containing the polymers for treating various surfaces and for use in various applications are also provided.

Polymers for use in cleaning compositions

A method of washing a soiled textile comprising cotton, the method comprising contacting the textile with a wash liquor, the wash liquor containing a soil-release effective amount of one or more soil release polymers obtained by polymerizing one or more polyisocyanates with one or more polymeric polyols having an average molar mass of above 1000 D and a 20&#xb0; C. water solubility of above 300 g of polymer per liter, one or more polyols having an average molar mass of below 12,000 D and a 20&#xb0; C. water solubility of below 100 g per liter, and optionally one or more further polyols.
